Uniting in language is a sign of increased communication and opportunity. The sooner we have a global language, the better. More opportunity, less duplicate code. I would think a bunch of engineers trying to create stuff would agree on that.

All of that being said, the study of language is very important, and the differences that exist should be recorded for scientific study. Maybe it even makes sense to preserve the real outlying communities (http://lambda-the-ultimate.org/) by forcibly cutting them off from the more general online communities.

But major languages (Java, Javascript, C#) are redundant standards that should be consolidated ASAP.
